Filed July 19, 1946 5 Sheets-Sheet 5 Inventor DU/VALD 0 .D/SBENNETPatented July 19, 1949 UNITED STATES PATENT OFFICE DIE Claims.

The present invention relates to new and useful improvements in dies foruse particularly in the manufacture of Us and has for its primary objectto provide, in a manner as hereinafter set forth, a device of thischaracter embodying a novel construction and arrangement wherebyproduction will be substantially increased as compared with means andmethods in use at present.

Another very important object of this invention is to provide a die ofthe aforementioned character which is adapted to be expeditiously openedto facilitate the removal of the finished article therefrom.

Other objects of the invention are to provide a die of the characterdescribed which will be comparatively simple in construction, strong,durable, highly efficient and reliable in use, compact and which may bemanufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

' Figure 1 is a view in side elevation of a die constructed inaccordance with the present invention.

' Figure 2 is a top plan view thereof.

Figure 3 is an end elevational view.

Figure 4 is a bottom plan view of the device.

Figure 5 is a view in vertical longitudinal section, taken substantiallyon the line 5-5 of Figure 2.

Figure 6 is a view in horizontal section through the device.

Figure 7 is a cross sectional view taken substantially on the line 'I'Iof Figure 1.

Figure 8 is a cross sectional view taken substantially on the line 88 ofFigure 1.

Referring now to the drawings in detail, it will be seen that referencenumeral I designates an end portion of a hollow cylinder havingapertured ears 2 therein. This end portion of the cylinder I furtherincludes an apertured external flange 3.

The ears 2 receive bolts 5 which project from one end of a core 6 formounting said core on the cylinder I in a manner to projectlongitudinally therefrom. The core 6 includes, on its forward endportion, a depending, removable bell I of substantially the shape shownto advantage in Figures 5 and '7 of the drawings. The lower, forward endportion of the core 6 is recessed, as at 8, to accommodate the upper endportion of the removable bell. A socket 9 in the upper end portion ofthe bell I accommodates a retaining pin III which has a shank portionthreaded into said forward end portion of the core 6.

Mounted on the cylinder I is a ring II which encircles the adjacent endportion of the core 6 in spaced, concentric relation thereto. The ringII includes, on one end, an external apertured flange I2 which isbolted, as at I3, to the flange 3 of the cylinder I. Headed pins I4project from diametrically opposite sides of the ring II, the purpose ofwhich pins will be presently set forth.

Rising from the ring I I is a longitudinally elongated eye I5. A shaftI6 is mounted in the eye I5. Suspended from the shaft I6 is a mold H thewalls of which are spaced from the core 6, including the bell I.

The mold II comprises a pair of complemental half sections I8 which arehinged at I9 on the shaft I6. Hooks 20 on the half sections I8detachably connect the mold I! to the ring II, said hooks beingengageable with the pins I4.

The mold II, it will be observed, is substantially in the form of anelbow and comprises a substantially bell shaped end portion 2| whichconforms to the shape of the lower portion of the member I. Dependinfrom diametrically opposite sides of the portion 2-I of the mold I1 is apair of fixed keepers 22. A double ended latch 23 is pivotally securedat an intermediate point, as at 24, on the bottom of the bell 'I. Theend portions of the latch 23 are engageable with the keepers 22 forsupporting the bell I in the mold I1 and for preventing the sections I8of said mold from opening.

It is thought that the operation of the device will be readily apparentfrom a consideration of the foregoing. Briefly, the clay is pressed intothe mold II around the core 6 with the bell 1 thereon until said mold isfull. The latch 23 is then disengaged from the keepers 22 and the bell Iis removed. The hooks 20 are disengaged from the pins I4 and the moldsections I8 are swung upwardly to open position on the shaft I6, assuggested in broken lines in Figure '7 of the drawings,

after which the L may be readily removed from the core 6, having beenpreviously severed through the medium of a suitable wire at the jointbetween the ring I I and the mold II. A nut 25 is threaded on one endportion of the shaft I6 for adjusting the mold II longitudinally. Afterthe L has been removed, the sections I8 are closed, the hell I isinserted and secured and the device is again ready for operation.

It is believed that the many services of a die constructed in accordancewith the present invention will be readily understood and although apreferred embodiment of the device is as illustrated and described, itis to be understood that changes in the details of construction and inthe combination and arrangement of parts may be resorted to which willfall within the scope of the invention as claimed.

Having described the invention, what is claimed as new is:

1. A die of the character described comprising a cylinder asubstantially elbow-shaped mold mounted on one end of the cylinder, saidmold including a pair of complemental hingedly con nected half sections,a core mounted on the cylinder and extending into the mold in spacedrelation thereto, said core having a recess on the end thereof remotefrom saidv cylinder said. core including a removable, angularlyextending end portion, and means for removably securing said end portionof the core in said recess comprising a retaining pin on said coreextendin into said recess, a socket in one, end of said end por tion toreceive said retaining pin, a latch carried by said. end portion, andkeepers on said sections to engage said latch,

2. A die of character described comprising a hollow cylinder, a ringmounted on one end of said cylinder, a rod mounted on said ring, asubstantially elbow-shaped mold including a pair of complemental halfsections hingedly suspended from the rod, a core rigidly mounted on thecylinder in spaced, concentric relationto the rin and the mold, saidcore including a removable, substantially right-angularly extending endportion, and means for-removably securing said end portion of the corein the mold.

3. A die of the characterdescribed comprising a hollow cylinder,aperturedears in said cylinder, a mold mounted longitudinally on oneend: of the cylinder and including a pairoi hingedly connectedcomplemental half sections, a core, and elements on said core engaged inthe ears for supporting said core onthe cylinder in spaced, concentricrelation-to the mold.

4. A die of the character described comprising a hollow cylinder,apertured ears in one end portion of said cylinder, a ring onzsaid'oneend of the cylinder, a rod mounted on the ring and projectinglongitudinally therefrom, a substantially elbow-shaped mold comprising apair oi complemental half sections hingecny suspended from the rod, acore, bolts projecting longitudinally from one end of the core andengaged in the ears for mounting said core on the cylinder in spaced,concentric relation to the ring and the mold, said core including aright angularly extending, removable end portion, means for detachablyconnecting the mold sections to the ring, and means for removablysecurin said removable end portion ofthe core in the mold.

5. A die of the character described comprising a hollow cylinder,apertured ears in one end portion of said cylinder, a ring on said oneend movable end portion of the corein' the mold, the

last-named means comprising fixed keepers de pending from the mold, alatch pivotally secured, at an intermediate point, on the removable endportion of the core, the end portions of said latch being engageablewith the keepers, said removable core portion having a socket therein;and a pin carried by the main portion of the core and engaged in thesocket.
